Upgrade to Python 3

The changes in this release upgrade the module to be used with Python versions >= 3.6. Given that Python 2 will reach end of life at the end of the year, these changes are not backwards compatible with Python 2.

Fixed property bug in EventProcessor.

Support Detail-Type in EventProcessor

Support was added for optionally specifying the CloudWatch even detail-type in the EventProcessor.
